.CORN-HARVESTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 423,469, dated March18, 1890.

i Application filed February 11, 1889. Serial No. 299,553. (No model.)

To all whom it may concern:

Be it known that I, JOHN R. CONKLIN, a citizen of the UnitedStates,residing at Wright township, in the county of Pottawatt-amie andState of Iowa, have invented a new and usey A ful Corn-HarvestingMachine, of which the following is a specification.

My invention relates to improvements in that class of corn-harvestingmachines which snap, break, or strip the ears unhusked from the stalks.

The objects of my improvements are to provide a machine that, when drawnor propelled by horses 'or other power Vover and along a row ofunharvested corn, will rapidly snap, break, or strip the ears of cornfrom the stalks and convey the same into a wagon which is drawn and keptbeside the machine; also, a machine that will leave the stalks standin gas straight after it has' taken the ears from them as they stood before;also, a machine that will take up stalks .that are down and strip andbreak the ears fromthem. I attain these objects by the mechanismillustrated in the accompanying drawings, in whic11- Figure lis aperspective view of the machinek Fig. 2 is a detail perspective view ofone of the elevators, one of the strippers, one of the beaters, and oneof the vibrating bars. Fig. 3 is a "detail perspective view ofthestrippers and of the sides of the elevators, to which they-arey secured,and of the cross-bar that is secured to the rear ends of the sides ofthe elevators; Fig. 4 is a detail perspective view of one of thevibrating-bar Fig. 5 is a vertical cross-sectional view of the machineon the line :c x of Fig. l. Fig. 6 is a vertical cross-sectional view ofthe machine on the' line `fy y of Fig. v1. Fig. 7 is a detailperspective Yview of the lower por tion of the rod a7.

Similar letters refer to similar parts th rough out the several views. y

The eight uprights a., the two uprights m4, the eight crossbars e, fourlongitudinal tim bers b, and two cross-bars mG constitute the frameof'the machine. y

The frames of the two elevators B are rmly secured to the sides of theframe, and the elevators are each composed of a bottom and the sides h2and as, the longitudinal iioor a9,

the sprocket wheels w w, and the endless sproket-chain 'm5, havingcross-lugs C17 secured 'to it.

D D are strippers. They rest upon and are iirmly secured by means ofscrews to the tops of the'sides as of the elevators, their-lower edgesbeing beveled to fit the top of the sides a8. They slant towardl eachother, and the apart to readily straddle a hill of corn. vThey are thewidest apart at their forward ends.

f E E are revolving beaters. naled at their forward ends to the supportsh3 h3, which arel secured to the strippers, and they are situated asufficient distance from the strippers to permit an ear of corn to passbetween the strippersand beaters when the beaters are revolving. Therods e7 e7 are firmly secured tothe rear ends of the beaters and passloosely1 through apertures in the supports es es. Theyfha'veiirmlysecured to their rear ends the'geanwheel's it', which engage and form abevel-gearing` with the wheels 113 i3, which are carried upon the'sliaftt3.

H is a vibrating bar. There are two of vnearly touch the ground, and arewide enough They are jourl them, one beside each stripper. They aresupported by the crank-shaped supporters as, which are pivoted at theirupper endsto the bars and at their lower portions .by means of the lugscito the elevators. The supporters a3 have ledges b2, which rest againsttheinward side of the lugs c4 and have their lower ends threaded toreceive a nut. The rods t4 t4 are pivoted at their forward ends to thebars H,

and have secured at-their rear ends the bands or straps c2c?, ywhichencircle the eccentricsu4 a4, which are carried upon the shaft t3. Theaxles n4 of the wheels g8 g3 pass loosely through apertures in the lowerends of the rear uprights da and in the lower ends of the uprights m4m4, and they arek revolved lbythe wheels"4 g3 g3 when gth'e ywheels g3'g3-are moved '-for`` Ward upon the ground by the forward 'movement ofthe harvesting-machine.

The gear-wheels fn 'n are firmly secured to the axles of the Wheels g3g3. The rods or shafts hv are journaled at their upper sends;

to the supports 7c 7c, and at their lower ends to lugs m7, that aresecured to the rear uprights;

a a. They have secured to them near their ends gear-wheels 5. The wheelsat theirlower ends engagewith and form a bevel-gearing with the zwheelsn mandlthose at their` yupper ends engage and form bevel-gearing withthe wheels 4 t4, that are secured to the shaft t3. The'sprocket-wheelmis secured to` the end 'of kthe shaftt, and is connected-by the;l

sprocket-"chain t with the 'sprocket-Wheelvm@ thatjissecured'to the endof the sh-aft a2. The vshaft 'ahasifrmly secured to it the sprocket.;

The-`crossbar -is vfirmly secured 'tofft--h rear ends of `the sides-a8a@ of the elevators.:` 'Dhefpoles c2 c2 are'pivotedrat their rear endsprights 'ct @,and have firmly-secured to thj i, r forward endsthefarched n'eckr-.yoke d2., The blocks yddjaresecured to theforwarduprights@ a, andhave Viirlnlyse'cu'red Vto th'etni thelpops rgg,fwhicl-i, with the blocks, forml 'slots through which the 'poles c2e2zpass, :The:

C `isa carrier 'constructed 'mainly like Vthe elevators. It is firmlysecured tothe finden y part of the elevators in such a position that Ytliefears `off/corn ivillfallffrom the `rear ends` ofth'efelevators intoit.
